    BIG LOPE

    This is the second one of these that I have used in two of my Hot Rods. Or should I say Street Rods. They make the most awesome engine lope. I know why and why Comp Cams designed these cams. I won't get into cam design. When people hear you coming, they stand up and move back out of the way. I absolutely love this cam and how it sounds.
